OBJECTIVE To review our 15‐year experience with ureteroscopic treatment of distal ureteric calculi and to determine the impact of improved technology and techniques on the efficacy, success and complications of the procedure. PATIENTS AND METHODS We retrospectively reviewed the medical records of 4512 patients who underwent 5133 ureteroscopic procedures for the treatment of distal ureteric calculi at our institution from January 1991 to December 2005. The patient and stone characteristics, treatment variables and clinical outcomes were assessed. Factors such as type of ureteroscope, procedure duration, procedure success, complication rate and hospital stay were evaluated. Data obtained from a cohort of patients that underwent the procedure from 1991 to 1995 (group 1) were statistical compared with those obtained from a cohort of patients from 1996 to 2005 (group 2). Logistic regression analysis was used to identify associated factors with the major complications of ureteroscopy. RESULTS Overall, the stone‐free rate after the procedure was 94.6%, the mean (sd; range) operative duration was 43 (15.0; 25–120) min, the intraoperative complication rate was 6.67%, the postoperative complication rate was 9.9%, and the mean (sd) hospital stay was 1.7 (1.1) days. The clinical and radiological follow‐up (mean 36.8 months) for 71.3% of eligible patients detected only 12 ureteric strictures (0.23%). On comparing group 1 with group 2, the overall success of ureteroscopic stone extraction improved from 85.7% to 97.3% (P < 0.001), significant ureteric perforation decreased from 3.3% to 0.5% (P = 0.05), ureteric avulsion decreased from 1.3 to 0.1% (P < 0.05), ureteric stricture decreased from 0.7% to 0.1% (P < 0.007), the mean (sd) procedure time significantly decreased from 75 (42.9) min to 36.5 (12.5) min (P < 0.001), and the mean hospital stay significantly decreased from 2.5 (1.6) days to 0.5 (1.2) days, with a trend toward outpatient treatment. Logistic regression analysis showed a significant association of the major ureteroscopic complications with increased operative duration, type of ureteroscope used, stone impaction, stone size and surgeon experience. CONCLUSION The present series shows the high success rate, with minor complications, that can be achieved with ureteroscopic treatment of distal ureteric calculi. Improvements in ureteroscope design, accessories, technique and experience have led to a significant increase in the success rate and decrease in the complication rate.

ObjectiveTo determine the incidence of symptomatic and ‘silent’ obstruction after ureteroscopic procedures.Patients and methodsIn all, 1980 patients underwent ureteroscopy for ureteric calculi in two large centres. The methods of disintegration, auxiliary procedures used and type of stenting were considered. Intraoperative complications, in addition to the size and site of the stone, were assessed in relation to postoperative obstruction. The mean (range) follow-up was 42 (12–68) months, with patients assessed after 3–6 months and yearly thereafter. The postoperative evaluation included an assessment of pain, renal ultrasonography, a plain abdominal film, intravenous urography, and a diuretic renal scan in some cases to confirm obstruction.ResultsThe success rate of stone removal was 98.5%. The failures were related to the size of the stone (>2 cm; P < 0.001). In eight patients there was a ureteric perforation, and six of these developed a ureteric stricture. A stricture also occurred in 12 patients (0.6%) during the follow-up; these included nine of 204 with stones of >2 cm (4.4%), compared to three (0.17%) of 1746 patients with stones of <2 cm (P < 0.001). Fourteen patients presented with pain (0.7%), and five had no obstruction, while in nine (0.46%) the pain was associated with obstruction. There was silent obstruction in three cases (0.15%). The negative and positive predictive values for pain were 99.8% and 64.3%, respectively.ConclusionsRadiographic surveillance for stricture formation and obstruction is mandatory in patients who are symptomatic after ureteroscopy, and for up to 18 months in patients with intraoperative complications or with a stone of >2 cm in the proximal ureter.

On the long term follow-up, most of the patients maintained their normal erectile and voiding functions with no harmful long-term complications. We advocate immediate surgical intervention and reconstruction of both corpora cavernous and urethra as a first line treatment for those patients.

Pregabalin appears to be a well-tolerated, safe and effective drug in reducing most of USRS, especially relief of pain with subsequent improvement of patient's quality of life. Its combination with solifenacin should be considered to manage patients with USRS as it shows a significant improvement in total USSQ score and general health index when compared to each drug alone.

ObjectiveTo evaluate the outcome of an intraprostatic injection of botulinum toxin-A (BTX-A) in men with refractory chronic prostatitis-associated chronic pelvic-pain syndrome (CP/CPPS) and to compare the efficacy of the transurethral and transrectal routes.Patients and methodsIn an uncontrolled randomised clinical trial conducted in men with refractory CP/CPPS, the patients were classified into two groups according to the route of BTX-A injection; transurethral (group 1, 28 patients) and transrectal ultrasonography-guided (group 2, 35 patients). The chronic prostatitis symptom index (CPSI), maximum urinary flow rate (Qmax) and white blood cell (WBC) count in expressed prostatic secretion (EPS) were measured before and at 3, 6 and 12 months after the injection. A significant clinical improvement (SCI, defined as a reduction of 4 points or a 25% decrease in total CPSI score) was correlated with patient age, prostate volume and symptom duration.ResultsIn group 1, the pain and quality-of-life domain scores improved, but statistically significantly only at 6 months. The voiding score improved at all follow-up visits. In group 2 there was a significant improvement in all the CPSI domain scores at all follow-up visits, except for pain, which was insignificantly improved by 12 months. The SCI ratings in groups 1 and 2 were 36%, 79% and 57%, and 49%, 89% and 74% in group 2 at the three follow-up visits, respectively. The Qmax was significantly improved in both groups during the follow-up (except at 12 months in group 1). There was a significant reduction in the mean WBC count in the EPS in patients with inflammatory prostatitis. Both prostate volume and symptom duration were significantly associated with a lower SCI rating.ConclusionBTX-A is an available treatment option for patients with refractory CP/CPPS. It is more effective in patients with a small prostate and short symptom duration. The transrectal route provided better results than the transurethral route. More prospective longer term studies are needed.

This study evaluated the use of traditional polypropylene mesh, used in hernias repair, as a sling in the treatment of female stress urinary incontinence (SUI). Forty patients diagnosed with SUI underwent transobturator sling fashioned from the ordinary polypropylene mesh (vypro II). Each lateral end of the tape is secured by a zero prolene suture. The procedure was then done outside-in, and the patients were followed up. The mean operative time was 40-60 min when the procedure was performed alone or accompanied with associated pelvic floor repair. Thirty-five patients (87.5%) were cured, and two patients (5%) significantly improved, but the procedure failed in three patients (7.5%), and the slings were removed because of vaginal erosion. Polypropylene mesh transobturator sling is an easy and cheap method for the treatment of female SUI with a high success rate.
